保存到数据库MVC模式

我对编程相当陌生，所以请原谅我。在整个项目中，我在不同的类中编写了以下代码，我想知道为什么我的输入没有存储在我的数据库中。我真的希望有人能帮助我，因为我已经为这个问题挣扎了几天了，清理了网络上最黑暗的角落。

首先，我应该告诉你，我的应用程序也在使用WCF -因此，方法应该通过WCFService调用到客户端。任何帮助将非常感激!

PS:如果它有帮助，这里是我的解决方案概述的截图:http://imgur.com/JV9Xl3K

  using Client.WCFServiceRef;  //My wcf Service reference
namespace Client
{
    public partial class MainWindow : Window
    {
        private WCFServiceClient Client;
        public MainWindow()
        {
            InitializeComponent();
            Client = new WCFServiceClient();
        }
        public string getMovieName()
        {
            string movieName = txtName.Text;
            return movieName;
        }
        public string getMovieLength()
        {
            string movieLength = txtLength.Text;
            return movieLength;
        }
        public string getMovieDesc()
        {
            string movieDesc = txtDescription.Text;
            return movieDesc;
        }
        private void btnMovies_Click(object sender, RoutedEventArgs e)
        {
            Client.addMovie(getMovieName(), getMovieLength(), getMovieDesc());
        }
    }
}

我的MovieController代码:

using Server.DB;
namespace Server.Control
{
    class MovieCtr
    {
        public void addMovie(string movieName, string movieLength, string movieDesc)
        {
            DBMovie conObj = new DBMovie();
            conObj.addMovie(movieName, movieLength, movieDesc);
        }
    }
}

My DBMovie Class

namespace Server.DB
{
    public class DBMovie
    {
        DBConnection dbCon = new DBConnection();
        public void addMovie(string movieName, string movieLength, string movieDesc)  
        {
            dbCon.openConnection();
            SqlCommand com = new SqlCommand();
            string query = "INSERT into movies (Name, Runtime, Description) VALUES  ('" + movieName + "','" + movieLength + "','" + movieDesc + "');"; 
            com.CommandText = query;

        }
    }
}

最后我的dbconnection类

namespace Server.DB
{
    public class DBConnection
    {
        SqlConnection sc = new SqlConnection();
        public void openConnection()
        {
            try
            {
                sc.ConnectionString = ("Data Source=balder.ucn.dk;Initial Catalog=dmaa0213_6;User ID=dmaa0213_6;password=XXXXXX");
                sc.Open();
            }  //endTry
            catch (SqlException ex)
            {
                Console.WriteLine("Could not open connection to database");
                Console.WriteLine(ex);
            }
        }
        public void closeConnection()
        {
            sc.Close();
        }
    }
}
